Unit tests for hostname task, not really good as hostname is machine
dependent, so writing a portable test is hard.
</description>
<target name="test1">
<a:unset name="hostname"/>
<a:hostname/>
<echo>hostname: ${hostname}</echo>
<a:assert name="hostname" exists="true" message="test 1 failed."/>
</target>
<target name="test2">
<a:unset name="localhost"/>
<a:hostname property="localhost"/>
<echo>localhost: ${localhost}</echo>
<a:assert name="localhost" exists="true" message="test 2 failed."/>
</target>
<target name="test3">
<a:unset name="localhost"/>
<a:hostname property="localhost" showall="yes"/>
<echo>all interfaces: ${localhost}</echo>
<a:assert name="localhost" exists="true" message="test 3 failed."/>
</target>
<target name="test4">
<a:unset name="localhost"/>
<a:hostname property="localhost" showall="yes" showip="yes"/>
<echo>all interfaces by IP: ${localhost}</echo>
<a:assert name="localhost" exists="true" message="test 4 failed."/>

Output:

test2:
[echo] localhost: blackdog
test3:
[echo] all interfaces: lo:127.0.0.1, eth0:, eth1:blackdog.somewhere.com, eth2:blackdog.wireless.somewhere.com
